OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 231,634, dated August24, 1880.

Application led June 23, 1880.

To all whom it may concern Y Be it known that I, PATRICK WALL, ofAllegheny, in the county of Allegheny and State ot' Pennsylvania, haveinvented anew and useful Improvement in Oil-Gans; and I do herebydeclare that the following is a fulll and exact description thereof,reference being had to the accompanying drawings, and to the letters ofreference marked thereon.

My invention relates to an improvement in oil-cans and it consists ofconstructing it ot' sheet-iron, brazing the joints and providing themwith protecting-rings, the upper end of said can forming the section ofa sphere, the outer edge of which is curved so as to project beyond thecylindrical portion of the body, and the bottoni dan ged and placedwithin thc lower Vend of the cylindrical part of the body, so that thelower edge of the cylindrical part will pro- 20. ject below the iiangeof the bottom and leave a single thickness ofmetal, which is turnedoutward for the purpose of holding the protecting rings in position onthe cylindrical part of the can, the said upper end of the can having onits inner wall a tubular and circular conduit for air, the inletandoutlet of which are near the same point, and so disposed withrelation to each other and the body ot' the can that the oil will notiiow through said conduit while manipulating the can in using it in theopera tion of oiling machinery.

To enable others skilled in the art With which my invention is mostnearly connected to make and use it. I will proceed to describe itsconstruction and operation.

In the accompanying drawings, which form partoi' my specication,Figure 1is a side elevation of my improvement in oil-cans. Fig. 2 is a verticalsection of the same. Fig. 3 is a perspective view of theprotecting-rings and handle, showing the latter coupled to the former.Fig. 4 is an inverted View of tho top, showing the arrangement oi' theair-conduit.

In the accompanying drawings, A represents the body of the can, B itstop, G its bottom, and D its oil-conveying tube, all of which areconstructed of sheet-iron andwith brazed joints. The top forms'a sectionofa hollow sphere, the edge of which is curved inward against the outerwalls of the body A, forming a curved projection at e, against which (N0model.)

the upper edge of the protecting-ring f rests. The bottom G is providedwith a. iiange, g, and is inserted in the body A, so that the walls ot'the body project below said ilange, which projecting portion of the wallis turned outward and over the lower edge of the protecting-ring h, asshown at fi in Fig. 2.

The protectingrings f h are coupled to the handle J, as shown in Figs. 2and 3, and are placed upon the body A at the points of the can which areusually injured by indentations made while manipulating the can in theoperation of oiling, particularly while oiling maf chineryin motion. Theprotectin g-rin gs f h are constructed, by preference, of semioval iron,

and are held iii position on the body A by means of the curvedprojection e of the top B, handle J, and the outward overlapping ot' thewalls of the body at i.

The oil-tube D is furnished with screw-threads K, which fit intoscrew-threads in the top B, which part of the top is made thick bybrazing a piece on its inner wall, forming sufficient thick# ness forforming screw-threads therein. On the under side of the topis secured anair-conduit, s,

which has an air-inlet at l with an outlet at m. d

The oil-conveying tube D is detached from the top B for supplying thecan with oil. In manipulating the can in the operation of oilingmachinery the flow of the oil through the oil-conveying tube D isarrested by the operator placinghis thumb over the air-inlet Z.

Vrlhe advantage of the oil-can herein described will be 'apparent tooperators of machinery in motion.

Having thus described my improvement, what I claim is- An oil-canconstructed of sheet-iron with brazed joints, the upper and lower-end ofthe cylindrical portion of the body surrounded with detachableprotecting-rings, the upper end of said can forming a section oit1 ahollow sphere, on the inner wall of which is arranged a circular conduitwith air inlet and outlet near the same point, substantially as hereindescribed, and for the purpose setforth.
